NN Asks: What did you learn from ANS’s Nuclear 101?
Mike Harkin
When ANS first announced its new Nuclear 101 certificate course, I was excited. This felt like a course tailor-made for me, a transplant into the commercial nuclear world. I enrolled for the inaugural session held in November 2024, knowing it was going to be hard (this is nuclear power, of course)—but I had been working on ramping up my knowledge base for the past year, through both my employer and at a local college.
The course was a fast-and-furious roller-coaster ride through all the key components of the nuclear power industry, in one highly challenging week. In fact, the challenges the students experienced caught even the instructors by surprise. Thankfully, the shared intellectual stretch we students all felt helped us band together to push through to the end.
We were all impressed with the quality of the instructors, who are some of the top experts in the field. We appreciated not only their knowledge base but their support whenever someone struggled to understand a concept.

Thermodynamic and transport property predictions for UF6-He gas mixtures are presented covering the operating range of conceptual, circulating gas core nuclear systems. The gas mixtures of interest contain 10 to 20% helium by mass, which corresponds to helium mole fractions of 0.9 and higher. For UF6 partial pressure <10 atm and temperatures in the range of 500 to 2000 K, mixture density can be determined from the ideal gas equation of state with an uncertainty of <10%. Compared to pure UF6, the thermal conductivity of the mixtures is an order of magnitude greater; specific heat is doubled while viscosity is changed very little. For identical systems, it is shown that heat transfer rates for UF6-He mixtures are five to six times greater than for pure UF6.
